Earth and Moon Viewer Welcome to Earth and Moon Viewer. Viewing the Earth You can view either a map of the Earth showing the day and night regions at this moment, or view the Earth from the Sun, the Moon, the night side of the Earth, above any location on the planet specified by latitude, longitude and altitude, from a satellite in Earth orbit, or above various cities around the globe. Images can be generated based on a full-colour image of the Earth by day and night, a topographical map of the Earth, up-to-date weather satellite imagery, or a composite image of cloud cover superimposed on a map of the Earth, a colour composite which shows clouds, land and sea temperatures, and ice, or the global distribution of water vapour. Viewing the Moon In addition to the Earth, you can also view the Moon from the Earth, Sun, night side, above named formations on the lunar surface. or as a map showing day and night.

Le Jardin japonais Les éléments du jardin L’architecte Ken Nakajima a choisi la péridotite, une pierre rare aux couleurs vernissées de serpentine vert émeraude, pour donner un cachet distinct à son aménagement. Les pierres utilisées ont été trouvées dans les mines d’amiante de Thetford Mines, dans l’est du Québec. Les plans du Jardin du thé ont été offerts par la Ville d’Hiroshima. Les poissons et les plantes Une carpe Koi peut vivre jusqu’à 50 ans. Le lotus ou « fleur de Bouddha » ne flotte pas à la surface de l’eau, comme le nymphéa, mais est plutôt ancré au fond de l’étang par une forte tige. Introduites au Japon au 8e siècle, les pivoines arbustives requièrent tant de soins que seuls les riches Japonais pouvaient se permettre d’en posséder.
Nasa announces space shuttle replacement shortlist 3 August 2012Last updated at 12:07 ET By Jonathan Amos Science correspondent, BBC News A Dragon made an unmanned flight to the space station in May We now have a much clearer idea of how American astronauts will get into orbit in the coming years. Nasa has selected three companies to help develop launch systems that can take people to the space station. They include the SpaceX firm, which recently sent an unmanned cargo capsule to the 400km-high outpost. But agreements have also been signed with aerospace giant Boeing and the Sierra Nevada Corporation. The agency has been working with a number of partners in recent years to find spaceflight capabilities that could replace its own shuttle fleet, which retired last year. Friday's announcement represented a reduction to concepts Nasa now thinks are best placed to deliver it a space transportation solution in the near-term. The agency's intention is to eventually outsource its crew launch requirements to the private sector. Refining designs

Nirgal.net : De la planète rouge à l'origine de la vie [Accueil] la Société des directeurs des musées montréalais – Activités culturelles, expositions et événements des institutions muséales de Montréal, Québec Planet with four suns discovered 15 October 2012Last updated at 11:33 ET By Paul Rincon Science editor, BBC News website The new planet - a gas giant - is about six times the size of Earth Astronomers have found a planet whose skies are illuminated by four different suns - the first known of its type. The distant world orbits one pair of stars which have a second stellar pair revolving around them. The discovery was made by volunteers using the Planethunters.org website along with a team from UK and US institutes; follow-up observations were made with the Keck Observatory. A report on the Arxiv server has been submitted to the Astrophysical Journal.

End QuoteDr Chris LintottOxford University The planet, located just under 5,000 light-years away, has been named PH1 after the Planet Hunters site. It is thought to be a "gas giant" slightly larger than Neptune - more than six times the radius of the Earth.
Home Skydiver Felix Baumgartner breaks sound barrier 14 October 2012Last updated at 18:17 ET By Jonathan Amos Science correspondent Highlights from Felix Baumgartner's leap into the record books Austrian Felix Baumgartner has become the first skydiver to go faster than the speed of sound, reaching a maximum velocity of 833.9mph (1,342km/h). In jumping out of a balloon 128,100ft (24 miles; 39km) above New Mexico, the 43-year-old also smashed the record for the highest ever freefall. He said he almost aborted the dive because his helmet visor fogged up. Footage from a camera on Baumgartner's chest shows out-of-control spin It took just under 10 minutes for him to descend. Once down, he fell to his knees and raised his fists in triumph. "Let me tell you - when I was standing there on top of the world, you become so humble. None of the new marks set by Baumgartner can be classed as "official" until endorsed by the Federation Aeronautique Internationale (FAI).

Helix Nebula General information Currently, the age is estimated to be 10,600+2,300 −1,200 years, based solely upon a measured expansion rate of 31 km·s−1. Structure The Helix Nebula is thought to be shaped like a prolate spheroid with strong density concentrations toward the filled disk along the equatorial plane, whose major axis is inclined about 21° to 37° from our vantage point. Expansion of the whole planetary nebula structure is estimated to have occurred in the last 6,560 years, and 12,100 years for the inner disk. Knots Closer view of knots in Helix The Helix Nebula was the first planetary nebula discovered to contain cometary knots. Its main ring contains knots of nebulosity, which have now been detected in many nearby planetaries.

3D printed moon building designs revealed 1 February 2013Last updated at 12:21 GMT The protective shell of the building is designed to be constructed on site by 3D printers Architects Fosters and Partners have revealed designs for a building on the Moon that could be constructed from material already on its surface. An inflatable structure would be transported from Earth, then covered with a shell built by 3D printers. The printers, operated by robots, would use soil from the Moon, known as regolith, to build the layered cover. The proposed site for the building is the southern pole of the Moon. It is designed to house four people and could be extended, the firm said. In 2010 a team of researchers from Washington State University found that artificial regolith containing silicon, aluminium, calcium, iron and magnesium oxide could be used by 3D printers to create solid objects. The latest plans are the result of a collaboration between a number of organisations including the European Space Agency. 'Fascinating and unique'
